| 中文摘要: |
| 蚂蚁与蜜源昆虫互作是物种间重要的关系之一，发挥着重要的生态功能。红火蚁Solenopsis invicta Buren是重要的入侵害虫，对生物多样性的影响已被熟知，但它与蜜源昆虫互作的生态学效应却不被充分理解。本研究评价了红火蚁与扶桑绵粉蚧Phenacoccus solenopsis Tinsley这两种入侵害虫之间的互作对寄生性天敌和粉蚧竞争性昆虫的影响。研究发现红火蚁的照看显著减少了寄主植物上粉蚧重要寄生蜂松粉蚧抑虱跳小蜂Aenasius bambawalei Hayat的种群数量，提高了寄主上粉蚧的存活率，有利于寄主上粉蚧种群的扩增和繁殖。同时红火蚁的存在也显著降低扶桑寄主上粉蚧竞争性昆虫美棘蓟马Echinothrips americanus Morgan成虫和幼虫的数量，抑制了美棘蓟马种群的竞争力，使得粉蚧可以占有更多的寄主植物，为粉蚧种群的繁殖提供了更好的条件。可见，红火蚁与扶桑绵粉蚧的互惠关系的生态效应可能是通过它们与多物种互作综合形成的结果。 |

| Interaction between ants and honeydew producing insects is one of the important relationships between different species and play an important ecological function.The red imported fire ant, Solenopsis invicta Buren is an important invasive pest and its impacts on biodiversity have been extensively recognized.However the ecological effects between S.invicta and honeydew producing insects have not been well known.This study evaluated the impact of interaction between two invasive pests S.invicta Buren and mealybug Phenacoccus solenopsis Tinsley on the parasitoid insects and mealybugs competitive insects.Our result found that the attendance of S.invicta resulted in a significant reduction in the population number of an important mealybug parasitic wasp (Aenasius bambawalei Hayat) on host plants; improve the survival rate of the mealybug, which is contributed to the amplification and reproduction of the mealybug population.Presence of S.invicta also significantly reduce the number |
